Blockchain Pitfalls Common pitfalls and correct patterns for blockchain interactions. When to Use - Making contract calls via RPC - Estimating gas for transactions - Handling reverts and errors - Managing nonces for concurrent txs - Configuring multi-chain support - Reviewing blockchain code Workflow Step 1: Verify Error Handling Check all contract calls are wrapped in try/catch. Step 2: Check Gas Estimation Ensure gas is estimated with buffer before sending. Step 3: Verify Multicall Safety Confirm multicall uses allowFailure: true. --- RPC Error Handling Gas Estimation Multi-Chain Configurat…
