Aomi Transact

Overview

Aomi Transact drives the aomi TypeScript CLI to build natural-language crypto agents and web3 assistants. It composes calldata, fork-simulates transactions as a batch, and stages wallet requests for explicit user signing — non-custodial throughout. Current chain metadata includes Ethereum, Polygon, Arbitrum, Base, Optimism, Sepolia, Linea, Monad, Monad Testnet, and local Anvil. The npm CLI is the production/end-user surface; the Rust aomi-cli in product-mono is an in-process dev/test CLI with different signing gates. For deep references, see commands.md, workflows.md, gotchas.md, account-abstraction.md, apps.md, examples.md, thread.md, drain-vectors.md, troubleshooting.md.

Prerequisites

• Node.js 18+ with npm or npx
• @aomi-labs/client v0.1.42 or newer: npm install -g @aomi-labs/client@latest
• For EVM signing: a 0x-prefixed private key via aomi wallet dev-key, --private-key, or PRIVATE_KEY
• For Solana sign-only flows: a base58 or JSON keypair via aomi wallet dev-key --solana, --solana-private-key, or SOLANA_PRIVATE_KEY
• Optional: AOMI_ACCOUNT_BEARER / --account-bearer for authenticated account-bound requests
• Optional: Alchemy or Pimlico credentials for direct account-abstraction providers; otherwise the CLI tries the backend Alchemy proxy path

Instructions

1. Detect or install the CLI: aomi --version 2>/dev/null || npx @aomi-labs/client@latest --version
2. Start a new thread: aomi chat "<task>" --new-session
3. Inspect queue: aomi tx list
4. For multi-step flows, simulate first: aomi tx simulate tx-1 tx-2
5. Sign: aomi tx sign tx-1
6. Verify: aomi thread status or aomi thread log

For the full procedure (read-only requests, building wallet requests, signing policy, batch simulation, secret ingestion), see workflows.md.

Examples

bash

aomi chat "what is the price of ETH?" --new-session
aomi chat "swap 1 ETH for USDC" --new-session --public-key 0xYourAddress --chain 1
aomi tx list && aomi tx simulate tx-1 tx-2 && aomi tx sign tx-1 tx-2
aomi chat "stake 0.5 ETH on Lido" --app lido --chain 1 --new-session

Four end-to-end walkthroughs (approve+swap, lending, bridging, staking) in examples.md. Per-app first-turn examples (Khalani, 0x, Polymarket, Binance, Neynar) in apps.md.

Output

• aomi chat: agent response or ⚡ Wallet request queued: tx-N
• aomi tx list: table of pending/signed tx ids with batch_status
• aomi tx simulate: per-step success/failure, revert reason, gas usage
• aomi tx sign: transaction hash and on-chain confirmation

Error Handling

Error	Cause	Solution
insufficient funds for transfer	EOA has no native gas	Fund EOA or configure AA sponsorship
AA execution failed with all modes	AA path failed after mode fallback	Read the per-mode errors; use --eoa only if the user accepts EOA gas/payment semantics
stateful: false in simulation	Wrong batch order	Reorder tx ids to match execution dependency
RPC 401/429	Rate-limited or missing key	Set --rpc-url to authenticated endpoint
No tx queued after chat	Agent returned quote first	Run aomi tx list; send a confirmation reply
Orphaned tx-N in list	Previous simulation failed	Only sign txs with batch_status: passed
Failed to get apps/models: HTTP 404	Public backend does not expose that introspection route	Treat app list/model list as backend-dependent; do not block chat/sign flows on it

Full troubleshooting in troubleshooting.md.

Safety Justification

This skill is risk_tier: L2 because it can sign and broadcast on-chain transactions. The permissions manifest enforces least privilege:

• Shell allowlist scopes execution to aomi and npx @aomi-labs/client@latest only — no arbitrary subprocesses.
• Network allowlist restricts outbound traffic to api.aomi.dev. User-supplied --rpc-url endpoints are resolved by the CLI itself; operators must review them before allowing signing.
• File scope is read+write to ~/.aomi/ only; identity files (SOUL.md, MEMORY.md, AGENTS.md) are deny-listed against writes per OWASP AST03 mitigation #3.
• No blind signing. Multi-step flows go through aomi tx simulate on a forked chain before aomi tx sign. Drain-vector calldata fields (recipient, onBehalfOf, mintRecipient, _to) are blocked at simulation time when they do not equal msg.sender — see drain-vectors.md.
• Opaque credentials. The skill never fabricates, derives, or echoes credential values; setup commands run only when the user explicitly asks and supplies the value in this turn. Full rules in gotchas.md → Hard Rules.

When to Use

• The user wants to chat with the Aomi agent from the terminal.
• The user wants balances, prices, routes, quotes, or transaction status.
• The user wants to build, simulate, confirm, sign, or broadcast wallet requests.
• The user wants to inspect or switch apps, models, chains, or threads.
• The user wants to inspect or change Account Abstraction settings.
• The user wants to authenticate a CLI account with aomi login, inspect it with aomi account, or inspect linked wallets with aomi wallet ls.
• The user wants to build a new app from an API spec or SDK — use the companion skill aomi-build.
