Accept, send, and manage ckBTC (chain-key Bitcoin). Covers BTC deposit flow via minter, ckBTC transfers, withdrawal to BTC, subaccount derivation, and UTXO management. Use when integrating Bitcoin, ckBTC, BTC deposits, or BTC withdrawals in a canister. Do NOT use for plain token transfers without BTC minting/withdrawal — use icrc-ledger instead.
Integrate wallets with IC dApps using ICRC signer standards (ICRC-21/25/27/29/49). Covers the popup-based signer model, consent messages, permission lifecycle, and transaction approval flows. Implementation uses @dfinity/oisy-wallet-signer. Do NOT use for Internet Identity login, delegation-based auth (ICRC-34/46), or threshold signing (chain-key). Use when the developer mentions wallet integration, OISY, oisy-wallet-signer, wallet signer, relying party, consent messages, wallet popup, or transaction approval.
