The complexity of modern smart contracts means that even a minor data mismatch can cause a halt. When ethers.js fails to process a request, it is usually due to a stale connection . Increasing the slippage tolerance slightly can help bypass a transaction that keeps reverting. Always keep a small reserve of native coins in your wallet to cover unexpected fee spikes.
A mismatch in the chain ID settings will prevent ethers.js from connecting to the network. Testing the proposed fix on a testnet is the safest way to ensure your funds remain secure. The transaction might be failing because the market price moved past your slippage limit. The move toward modular blockchain layers has introduced new types of synchronization errors.
Layer 2 network delays can sometimes lead to «ghost» transactions that appear later.
