Changelog

Updated dependencies [2c2ddb6, 7ca4af6].

Add blockchain.payment.settled_amount: the amount the settling party reports it settled, recorded as reported next to blockchain.payment.amount, which keeps the amount the payer knew.

Add @hashspan/x402: withHashspan(client, { reader }) registers hooks on an x402Client, so each payment made through @x402/fetch, @x402/axios or @x402/mcp becomes a payment {chainId} span with the payer, recipient, asset, amount, scheme,…

Traced CDP calls now run while their send span is the active span, so spans that HTTP instrumentation creates for the CDP API request nest under the send span instead of beside it (ADR 0015).

sendTransaction and writeContract now run while their send span is the active span, so spans that wallet, RPC or HTTP instrumentation creates for the call nest under the send span instead of beside it (ADR 0015).

Deprecate the value timeout of blockchain.tx.status and the constant BLOCKCHAIN_TX_STATUS_VALUE_TIMEOUT (ADR 0016).

withHashspan(cdp) accepts a CdpClient of the CDP SDK in TypeScript.

Tracing writeContract no longer runs getters inside the ABI.

Tracing no longer runs getters on call arguments.

Add @hashspan/cdp: withHashspan(cdp, { reader }) traces transactions sent by Coinbase CDP server accounts (cdp.evm.sendTransaction, each account's sendTransaction, transfer, swap, useSpendPermission and network-scoped sends, and execute()…

Add watch(client, { hash, chainId?, timeoutMs?, abi? }) to the withHashspan() result: it confirms a transaction sent outside the extended clients, such as by a wallet API, in the background, with the receipt, revert reason and fees, linked to a send…

SendHandle.fail(error, endTime, { errorType }) records a library's machine-readable error code as error.type instead of the error's class name, when it is a short identifier ([A-Za-z0-9_.-], at most 64 characters).

A field set in the static agent option now always wins over the Baggage entries gen_ai.agent.id / gen_ai.agent.name; Baggage only fills fields the option leaves unset.

Add confirm: { mode: 'background' } to withHashspan(): sent transactions are confirmed without an explicit wait and without delaying the send.

Add createTxTracker(), the transaction lifecycle tracker.
