Wallet, signing and on-chain integration for web apps

Wallet integration is mostly failure handling: the user rejecting, the chain being wrong, the gas estimate being stale, the nonce colliding. We build those paths first, because they are the ones users hit.

What is included

• Connect and sign-in flows across the major wallets and both EVM and Solana where needed.
• Correct network detection and switching, including chain-wrong states.
• Gas estimation, batching and nonce management that survive concurrent submissions.
• Every failure state designed and reachable, not just the happy path.

How the work runs

1. Map the workflowWe break down your process and identify what an agent can own end-to-end.
2. Design the agentModel selection, tool access, guardrails, on-chain permissions — designed with you.
3. Build & simulateAgents tested in sandbox simulations; contracts rehearsed on testnets first.
4. Deploy & monitorProduction launch with monitoring, alerting, and continuous improvement.
