ETH to Native BTC: THORChain Delivery & Refunds

Connect both destination identities

Connect an ordinary Ethereum wallet and a UniSat Bitcoin mainnet P2WPKH payment account. The Bitcoin address is checked for its network and checksum. This adapter enables ETH to BTC only; it does not spend native BTC or substitute a wrapped-BTC token.

Inspect a fresh route

Enter ETH with at most eight decimals. Find route checks current vault addresses and trading halt flags with two THORChain nodes, then obtains pricing. Inspect protocol/outbound fees and set the minimum BTC received. A changing quote or vault invalidates execution. Keep ETH for gas and sign promptly after review.

Distinguish deposit from delivery

The wallet signs an Ethereum router deposit binding the vault, native amount, BTC recipient and minimum-output memo. Its finalized receipt proves the source deposit. THORChain then executes and schedules the destination transfer; this process is not globally atomic and can be delayed or refunded.

Verify BTC or recover a refund

Bitpont checks the matching THORChain outbound, exact Bitcoin transaction bytes, recipient, source-linked memo and at least six canonical confirmations through two Bitcoin providers. A refund reported by THORChain stays unverified until finalized native ETH payment can be proved with an RPC trace. Import the Ethereum source hash to resume tracking. Do not repeat a source deposit while delivery remains unknown.
