Documentation

Integrate Defimec into your signing workflow.

Quickstart guide, REST + WebSocket API reference, and per-chain configuration for Solana, Base, and Arbitrum.

defimec init

# Install Defimec SDK
npm install @defimec/sdk

# Initialize with chain config
import { Defimec } from '@defimec/sdk'

const dfm = new Defimec({
  chains: ['solana', 'base', 'arbitrum'],
  ledger: { transport: 'webusb' },
  rpc: { healthProbe: true },
})

Quickstart

Get from install to your first verified signing in under 10 minutes. Covers SDK setup, chain configuration, and a basic swap signing example.

API Reference

Complete REST and WebSocket API documentation. Endpoints for signing, verification, RPC health, and calldata decoding.

Chain Configuration

Per-chain RPC configuration, chain-ID registry, Solana program account setup, Base/Arbitrum network parameters, and health probe settings.

Key topics

Common integration patterns

Chain-ID lock

Configure the chain-ID enforcement policy so every signing request is pre-verified against the declared network. Prevent stale-RPC misdirection.

See configuration

RPC health probe

Programmatically probe each configured RPC endpoint before routing a transaction. Detect poisoned or stale nodes before your hardware is involved.

API endpoint

Calldata decode

Decode raw calldata into human-readable instructions before signing. Supports ERC-20 transfers, DEX swap payloads, EIP-712 typed-data, and Solana instruction decoding.

Decode API

Multisig signing

Coordinate multi-signer approvals across chains. Each signer gets a decoded view of the exact transaction they're approving. Treasury tier only.
