Cross-Platform Immunity
Genes learned from Tempo and Privy protect Coinbase workflows automatically.
| Tempo Gene | Coinbase Scenario | Category | Q-Value |
|---|
| nonce_desync | AA25 Invalid nonce (Paymaster) | B - nonce_refresh | 0.88 |
| rate_limit_429 | rate_limit_exceeded (CDP) | A - retry_backoff | 0.92 |
| gas_estimation | GAS_ESTIMATION_ERROR (Paymaster) | B - gas_bump | 0.85 |
| insufficient_funds | insufficient USDC (x402) | C - topup | 0.79 |
| rpc_timeout | timed_out (CDP) | B - rpc_switch | 0.91 |
Safety Modes
Three execution tiers. Default is observe (zero risk).
observe (default)
Diagnose only. Zero execution. Zero risk. Perfect for CI and monitoring.
auto
Execute Category A+B (retry, nonce refresh, network switch). No fund movement.
full
Execute Category C (swap, split, topup). Requires cost ceiling. Fund movement enabled.
MCP + API Integration
Connect Helix to Coinbase AgentKit via 5 MCP tools.
AgentKit Integration
import { Helix } from '@helix-agent/core';
import { CdpAgentkit } from '@coinbase/cdp-agentkit-core';
const helix = new Helix({ mode: 'auto' });
const kit = await CdpAgentkit.configureWithWallet();
// Wrap any AgentKit call
try {
await kit.transfer({ to, amount });
} catch (err) {
const result = await helix.diagnose(err);
// result.strategy, result.gene, result.reasoning
}
