FRAME TRANSACTIONS, SIMPLIFIED

One client.
Every frame.

A familiar developer experience for native account abstraction. Prepare, sign, and send EIP-8141 transactions with a few typed viem actions.

Your client, with frame superpowers.

Client reference

Keep viem’s transport and public actions. Add an explicit frame lifecycle on top of the workshop’s existing codec.

framepay.ts
// Extend your viem client with native frame actions.const client = publicClient.extend(  frameActions({ profile: 'ethrex-eip8141-tracer' }),);const signed = await client.signFrameTransaction({  transaction, signer,});const hash = await client.sendFrameTransaction({  transaction: signed,});const receipt = await client.waitForFrameReceipt({ hash });
This excerpt assumes a configured client, prepared transaction, and signer. Follow the full quickstart.

Small surface. Useful primitives.

Typed from the start

Explicit frames, fees, and nonces. Clear inputs for every action.

See every frame

Separate a mined transaction from successfully executed frames.

Know what happened

Read admission decisions and the rules behind a rejection.

A focused developer preview

The current SDK targets the local ethrex workshop profile. Provider sponsorship quotes, PQ accounts, and pre-submission simulation are on the roadmap.
