Solv Protocol

Solv Protocol is an on-chain Bitcoin reserve and yield infrastructure layer that wraps deposited BTC into a 1:1 liquid token called SolvBTC, then routes that liquidity into institutional yield strategies across more than 22 blockchains—including Solana—while keeping reserves verifiable in real time through Chainlink Proof of Reserves oracles.

What It Does

Bitcoin has historically been a passive asset: holders either self-custody and earn nothing, or hand control to centralized platforms that offer opaque yield. Solv Protocol addresses this by acting as a programmable reserve layer that tokenizes Bitcoin into productive, transferable representations without relying on a single custodian.

The result is a suite of three products:

• SolvBTC — a universal, 1:1 BTC-backed token that standardizes fragmented wrapped BTC representations (WBTC, cbBTC, BTCB, tBTC, FBTC) into a single fungible asset usable as collateral on lending markets, DEX liquidity pools, and partner exchange earn programs.
• xSolvBTC — a yield-bearing SolvBTC variant with instant redemption, designed for on-chain DeFi users deploying into lending protocols, liquidity pools, or structured products on Morpho, Venus, and Pendle.
• BTC+ — an automated allocation vault that routes capital into risk-adjusted, diversified yield strategies. BTC+ has a native Solana program deployed with its own vault and mint addresses on-chain.

How It Works

When a user deposits BTC or an accepted wrapped-BTC variant, Solv mints an equivalent amount of SolvBTC. The underlying assets are held in a Decentralized Reserve Network secured by FROST (Flexible Round-Optimized Threshold Signatures), a threshold-signature scheme that distributes signing authority across a decentralized node set. No single node or custodian can move funds unilaterally, eliminating the single point of failure present in traditional multi-sig or centralized custodian models.

Holders who want yield stake their SolvBTC through the Staking Abstraction Layer (SAL), a standardized interface that aggregates multiple external yield protocols behind a single entry point. The SAL governs how capital is deployed through a Staking Parameter Matrix (SPM), which sets technical parameters, script configurations, and reward distribution rules for each strategy. Current yield strategies include:

• SolvBTC.BBN — BTC staking on Babylon Network
• SolvBTC.ENA — CeDeFi strategy through Ethena
• SolvBTC.JUP — Liquidity provision in Jupiter Exchange pools on Solana, targeting roughly 12% BTC-denominated net APY after hedging
• SolvBTC.CORE — Bitcoin sidechain yield on Core Network (~4% annual)

The SAL decouples reserve security from yield execution: the underlying BTC reserve remains in the FROST network while yield strategies operate on the staked positions, so reserve integrity is not compromised by individual strategy risk.

Solvency is verified continuously through Chainlink Proof of Reserves, which publishes the protocol's backing ratio on-chain. According to the protocol's transparency dashboard, the backing ratio has remained at 100%, and reserves are subject to weekly third-party proofs and monthly custodian attestations.

Cross-chain bridging uses a burn-and-mint mechanism. Chainlink CCIP handles most chains, LayerZero covers Ethereum and Starknet, and Axelar connects Stellar.

Solana Integration

Solana is one of Solv's 22+ supported chains. SolvBTC arrives on Solana via Chainlink CCIP. The BTC+ vault runs as a native Solana program with vault address B3ct2h3iCWKZmErPQ8PtZ51qBU98Zfci2TSnjvXNUbUa and mint SoLvHDFVstC74Jr9eNLTDoG4goSUsn1RENmjNtFKZvW, with source code published at solv-finance/SolvBTC-Solana-Contract on GitHub.

The flagship Solana yield product is SolvBTC.JUP, launched October 2024, which deploys SolvBTC as liquidity into Jupiter DEX aggregator pools on Solana. The strategy targets approximately 12% BTC-denominated net yield after hedging out net open interest through centralized exchange positions. The product was integrated via InterportFi and Chainlink CCIP, bringing Bitcoin liquidity to one of Solana's most active DeFi venues. Three products are now live on Solana: SolvBTC, xSolvBTC, and SolvBTC.JUP.

Key Metrics

At the time of most recent homepage data (May 2026), the protocol held:

• $582M TVL
• 9,205 BTC in reserves
• 325+ integrated projects
• 22+ supported chains
• 1.2M users across 73 countries
• 268+ partnerships

At its 2024-2025 peak, TVL reached approximately $2.5B with over 28,000 BTC deposited, placing Solv among the top five largest on-chain Bitcoin holders globally.

SOLV Token

The protocol's native governance and utility token is SOLV, with a maximum supply of 9.66 billion (genesis supply 8.4 billion). It was distributed partly through a Binance Megadrop (7% of genesis supply) and is listed on Binance. Token utility includes governance voting, staking for protocol emissions on the SAL, and fee discounts including SolvBTC redemption fees.

Token allocation: private sale investors (28.86%), community rewards and DAO treasury (18%), team and advisors (13%), community airdrop (8.5%), external partner rewards (8.5%), ecosystem development (8.14%), Binance Megadrop (7%), business development (4%), liquidity (3%), vesting voucher holders (1%), and a Bitcoin Reserve Offering tranche (13.04% of max supply).

The Bitcoin Reserve Offering (BRO) is a convertible note mechanism: Solv issues 42M SOLV per tranche in exchange for capital that acquires BTC into protocol-owned reserves. Three BROs were scheduled for Q1-Q3 2025, with notes maturing over one year. The model is positioned as protocol-owned Bitcoin accumulation, similar in concept to treasury accumulation strategies seen at public companies.

Team and Funding

Solv was founded in 2020. Key founders include Ryan Chow (CEO), Will Wang (co-creator of ERC-3525, the Semi-Fungible Token standard, with 20+ years in financial technology), and Meng Yan (former VP of CSDN). Total disclosed funding exceeds $40M across multiple rounds, with lead investors including Blockchain Capital, OKX Ventures, Laser Digital, and Yzi Labs.

Security

Smart contract audits have been conducted by Quantstamp, Salus, CertiK, SlowMist, and Secbit. Audit reports are published in the solv-finance/Audit GitHub repository. Chainlink Proof of Reserves provides continuous on-chain solvency verification, and the Solv Guard system uses Safe multi-signature wallets with Vault Guardians that whitelist permitted contract addresses and functions.

In March 2026, a smart contract exploit drained approximately $2.7M from a single Bitcoin Reserve Offering vault, affecting fewer than ten users. Solv publicly disclosed the incident, engaged Hypernative, SlowMist, and CertiK for post-incident reviews, and deployed additional mitigations. A public bug bounty program runs through HackenProof.

Ecosystem Fit

Solv occupies the intersection of BTC liquidity and multi-chain DeFi, serving a user base that wants Bitcoin yield without centralized counterparty risk. Its Solana presence through SolvBTC, BTC+, and SolvBTC.JUP extends that infrastructure to one of the most active DeFi ecosystems, giving Solana protocols and users access to BTC-denominated yield strategies that compound within the Solana DeFi stack rather than requiring users to bridge to other chains.
