Keep Network (KEEP) research overview
Keep Network (KEEP) is tracked by YearBull under the source identifier keep-network. Source categories place the asset in the Layer 1 Cryptocurrencies universe, with additional labels including Smart Contract Platform, Decentralized Finance (DeFi), Harmony Ecosystem. Category labels describe market context; they do not prove project activity, adoption, or investment quality.
Market structure and supply
Observed market capitalization is about $19.97 million and reported 24 hour volume is about $1.1 thousand. That volume equals 0.01% of market capitalization in the dated snapshot. Current circulating supply is 965,210,762. The recorded maximum supply is 1,000,000,000. Circulating supply changed +75.6% across the available historical window. Reported volume and supply fields can change through source revisions, issuance, burns, migrations, or venue coverage.
Key risks and limits
Validator or miner concentration, client faults, network outages, token issuance, ecosystem activity, bridges, and governance are material dependencies. High YearBull Risk appeared on 0.8% of stored observations. Historical metrics describe the available YearBull record; they do not predict future returns. Contract addresses, network support, custody, and venue availability should be verified before use.
Primary sources and review scope

Keep Network (KEEP): From Private Data Containers to Threshold’s Bitcoin Infrastructure
Keep Network introduced off-chain privacy infrastructure and threshold-signing tools for Ethereum applications. Its most important legacy contribution is now carried forward through Threshold Network, while KEEP itself has been superseded by the T token.
What Keep Network was built to do
Keep Network was designed to let smart contracts use private information without placing that information directly on a public blockchain. Its central concept was the “keep”: an off-chain container managed by a group of network operators. Applications could open, manage, and close keeps through smart contracts, while the data and computation remained outside ordinary public contract storage. This model targeted applications that needed confidentiality, cross-chain coordination, or private key management rather than another general-purpose blockchain.
The project’s public materials presented privacy-focused infrastructure as the broader use case, but the most concrete implementation work centered on threshold cryptography and decentralized signing. The system was intended to distribute control of sensitive key material among multiple operators, so that an application could request a signature without handing a complete private key to one party. This distinction matters: Keep was primarily an infrastructure layer for applications on Ethereum, not a standalone smart-contract platform competing to host ordinary user transactions.
How keeps and threshold signing worked
Keep’s reference implementation described stakers as node operators who maintained keeps and received fees for network services. When a keep was created, a group of operators was selected through sortition using a random-beacon mechanism. The design was intended to make group selection difficult to predict and to avoid assigning every task to a fixed committee. The repository identifies the BondedECDSAKeep as the first major keep type: it allowed contracts to generate distributed ECDSA key material and request signatures for cross-chain or custodial workflows.
This architecture introduced several practical dependencies. The cryptographic protocol had to produce valid signatures, the selected operators had to remain available, Ethereum contracts had to coordinate requests and timeouts, and the economic incentives had to cover operating costs. Keep’s own random-beacon RFC records operational problems in an earlier version, including Ethereum hard-fork disruption, complex gas-price reimbursement, and timeouts that could make small groups uneconomic. Those details show that threshold cryptography does not remove operational risk; it moves part of the trust model into software, committee selection, incentives, and node availability.
tBTC and the project’s most visible application
The best-known Keep application was tBTC, a system for representing Bitcoin on Ethereum without relying on a conventional centralized custodian. Keep’s legacy tBTC repository describes the asset as a Bitcoin-backed ERC-20 and identifies the use of threshold-controlled Bitcoin wallets as part of the design. The repository also states that its first-generation code is archived and no longer actively maintained, having been superseded by tBTC v2. New readers should therefore distinguish the historical Keep/tBTC v1 codebase from the later Threshold implementation.
The application logic is easier to understand than the branding: Bitcoin is deposited into a wallet controlled by a distributed signer group, while an Ethereum token represents the corresponding claim. Users and DeFi protocols then interact with the token on Ethereum. The security question is not simply whether the ERC-20 contract works; it also concerns Bitcoin wallet control, signer coordination, redemption rules, Ethereum contracts, and the procedures used when components fail. Threshold’s current website presents tBTC as the continuing product of the Keep and NuCypher merger, but those claims should be evaluated separately from the historical KEEP token.
The merger changed the project’s identity
Keep Network did not remain an independent protocol under its original identity. The Keep website states that Threshold Network was formed through a merger of Keep Network and NuCypher, and the current Threshold code repository describes itself as the smart-contract and reference-client codebase behind Threshold Network. This makes the old Keep repositories useful for understanding architecture and history, but not necessarily a guide to the current production system.
The transition also creates a naming risk for users. The Keep homepage currently instructs holders of KEEP and NU to upgrade to the T token. In practical terms, KEEP should be treated as a legacy asset associated with the pre-merger network, while Threshold’s current governance and services use the post-merger token system. Wallets, bridges, exchanges, and applications may not support the same migration path, so an address or ticker match alone is not enough to establish that a token is the intended asset.
What role remains for KEEP
KEEP’s historical role was tied to staking, operator participation, and economic security for Keep services such as ECDSA signing and tBTC infrastructure. The legacy core repository describes stakers as node operators who could earn fees, while the original tBTC materials discuss KEEP-related incentives and protocol operations. Those functions should not be presented as current standalone utility without checking the post-merger documentation and the applicable migration contracts.
For current readers, the central analytical question is therefore not whether KEEP has an interesting historical design. It is whether the asset still has a supported, enforceable role after the move to Threshold and the introduction of T. The available first-party material clearly documents the migration direction, but it does not by itself establish that every venue, wallet, or application has preserved liquidity or functionality for legacy KEEP.
Users, dependencies, and practical limits
The intended users were developers building privacy-preserving applications, cross-chain systems, Bitcoin-to-Ethereum infrastructure, and custodial or signing workflows. Today, Threshold positions its infrastructure toward DeFi users, institutions, and developers seeking Bitcoin integrations. The common dependency is distributed cryptographic coordination: applications depend on smart contracts, node operators, threshold-signing implementations, Bitcoin and Ethereum availability, and governance decisions that can alter parameters or migration procedures.
The principal limitations are structural. A distributed signer group can still suffer from software defects, correlated operator failures, unavailable nodes, flawed incentives, or governance mistakes. Bridge users also face risks spanning two blockchains and several contract layers. Archived repositories add another maintenance concern: historical code may remain valuable for research while no longer receiving active fixes. For KEEP specifically, migration ambiguity and thin support for a legacy token may be as important as the original protocol design.
Key takeaways
- Keep Network focused on private off-chain containers and threshold-controlled signing for Ethereum applications.
- The BondedECDSAKeep design distributed signing authority among selected stakers rather than placing a complete private key with one operator.
- tBTC was the clearest Keep use case, but the original tBTC repository is archived and has been superseded by tBTC v2.
- Keep and NuCypher merged into Threshold Network, changing the project’s operating identity and token framework.
- The Keep website directs KEEP holders toward migration to the T token, so legacy KEEP utility should not be assumed.
- Security depends on cryptography, smart contracts, operator availability, incentives, Bitcoin custody rules, and governance together.
Risks and open questions
- Legacy-token risk: KEEP has been superseded in the project’s stated migration path, but support can differ across wallets, venues, and applications.
- Bridge risk: tBTC depends on Bitcoin wallet control, distributed signers, Ethereum contracts, redemption logic, and operational availability.
- Code-maintenance risk: the original tBTC repository is archived, and historical Keep components may not represent the current production implementation.
- Governance and migration risk: changes to token contracts, upgrade procedures, or network parameters can affect holders and integrators.
- Operator-concentration and availability risk: threshold systems remain dependent on the selected node set and its ability to coordinate signing.
- Evidence gap: first-party pages document the migration direction but do not establish current liquidity, venue support, or active utility for every KEEP deployment.
YearBull Rank timeline
Latest available YearBull Rank for keep-network: #7749.
Rank movement (nearest daily data).
Reading rule: a smaller rank number indicates stronger placement.
- 7d window (2026-10-20): #5705 → #7749 (down by 2044).
- 30d window (2026-09-27): #1460 → #7749 (down by 6289).
YearBull Rank is a relative placement score used on YearBull to compare a coin against peers within the same dataset. A smaller rank number indicates a stronger position at that moment.
Cycle context: If the 30d is noisy, increase the lookback to avoid over-reading. cycle shifts often show up as slope changes, not spikes.
Liquidity angle: If the line only moves on high-volume days, liquidity is a key filter. relative rank is sensitive to who is active in the window.
Listing context: If the line breaks range, confirm it across a longer window. a new route can show up as a step change.
Risk note: If it is flat for long, the coin may be tracking the cohort. big jumps can be data-driven, but also rotation-driven.
Practical note: rank is relative by design, so peers matter.
