Bitcoin is coming to Umi.
And it’s arriving through BitcoinOS (BOS), the operating system that allows BTC to move into other ecosystems with ZK-secured cryptographic integrity.
This integration enables BTC to migrate to Umi Network as eBTC, a BOS-enchanted asset that is portable, programmable, and verifiable—ready to be used across Umi’s high-speed MoveVM and EVM environments.
🔄 eBTC: Bitcoin That Works Where You Build
Powered by the Charms metaprotocol, BOS unlocks Bitcoin's participation in advanced, cross-chain DeFi and smart contract systems. With Charms, BTC becomes a programmable token portable to any chain, secured by zkSNARKs rather than trusted intermediaries or multi-sig federations.
On Umi, eBTC appears as a fully native token—usable across all MoveVM and EVM-based applications.
🚀 Why Umi? Multi-VM Composability Meets Bitcoin Liquidity
Umi brings the best of both smart contract worlds: high-assurance development via Move, and mass-compatibility via EVM. Now, developers on Umi can access Bitcoin’s deep liquidity to build:
- Lending platforms powered by eBTC collateral
- DEXs and cross-chain swaps involving BTC and ETH
- Composable contracts that use eBTC across both VMs
By combining Umi’s execution layer with BOS’s ZK asset rails, builders gain scalability and security without friction.
🔐 ZK Security: How BOS Brings BTC to Umi
BOS leverages BitSNARK, a minimal zk-verifier optimized for Bitcoin, and the Grail bridge architecture. This enables a simple, secure transfer process:
- BTC is deposited into a Taproot vault controlled by a zkSNARK-enabled locking script.
- A proof of deposit is generated and verified by operators and clients.
- eBTC is issued on Bitcoin as a representation of the locked BTC, transferable to and usable within Umi’s smart contract environments.
- Users can burn eBTC later and generate a proof to redeem BTC from the original vault on Bitcoin.
The system operates under a 1-of-N security model, where any honest verifier can enforce correctness, and all proofs are validated client-side with no need for external trust assumptions.
🛠 What This Unlocks for Builders
With eBTC live in the Umi ecosystem, developers can now:
- Launch DeFi protocols with eBTC collateral
- Build cross-chain arbitrage bots that operate across Move and EVM liquidity pools
- Enable NFT marketplaces, lending, and DAOs powered by BTC
- Use BOS tooling and ZK proofs to verify and move eBTC across chains
This is BTC as a global value layer, ready for high-performance applications and composable financial systems.
🔭 The Next Era for Bitcoin and Umi
This partnership is a pivotal moment in BOS’s roadmap to scale Bitcoin across the modular Web3 stack. Umi is now part of a growing network of ecosystems gaining access to:
- eBTC as programmable liquidity
- Charms as a chain-agnostic smart asset layer
- Grail as a ZK-secured BTC bridge
The integration with Umi showcases the real-world viability of programmable Bitcoin—and turns the BTC capital base into active liquidity across the most advanced infrastructure stacks.
