exSat is a Bitcoin Docking Layer built on EOS/Antelope, bridging native BTC into an EVM-compatible execution environment via a federated custodian bridge.
How exSat mirrors Bitcoin's UTXO data on-chain, then wraps it as 1:1 XBTC.
A new block is mined on Bitcoin L1, carrying the latest UTXO changes. exSat does not touch Bitcoin — it observes and mirrors it.
Permissionless nodes that race to submit each Bitcoin block's raw data to the native layer, competing PoW-style for XSAT rewards.
Staked nodes that verify the submitted data and reach consensus on the canonical UTXO state before it is indexed.
The exSat native layer (EOS/Antelope, C++ contracts) indexes Bitcoin's UTXO set; the EVM execution layer (ChainID 7200) is permissionless, but the underlying BTC is held off-chain by a regulated custodian federation with no unified on-chain proof-of-reserves.

Bitcoin generates no native yield and cannot interact with smart contracts. Existing BTC bridges suffer from federated-custody risk (Ronin, Multichain) or rely on wrapped-asset issuers with limited transparency.
exSat provides a custodian-federated bridge to mint 1:1 XBTC on an EVM-compatible execution layer built on EOS/Antelope, then offers BTC staking that earns XSAT rewards while a regulated custodian set (Ceffu, Cobo, ChainUp, Cactus) holds the underlying BTC.
Built on EOS/Antelope rather than a standalone L2, leveraging EOS RAM and the high-throughput Antelope toolchain. Operates with a regulated custodian federation rather than a permissionless multisig. XSAT follows a Bitcoin-style fair launch with no pre-mine or pre-allocation.
