Layer2 & EVM

EVM-compatible networks, gas, permissions, Layer2, cross-layer transfers and bridge security.

EVM-compatible Networks

EVM-compatible networks use similar smart-contract execution environments, but each has independent chain IDs, RPCs, gas assets, contracts and block explorers. Similar address formats do not mean assets can move directly between networks.

Network Parameters & Gas

When adding a network, verify the network name, chain ID, RPC and block explorer source. Before sending or calling contracts, have the correct gas asset and remember fees can change with congestion.

Contract Permissions & DApps

Token approvals allow contracts to use assets within a defined scope. Before approval, verify the site, contract address, allowance and purpose. Fake tokens, malicious contracts and phishing DApps can create risk.

Layer2 & Cross-layer Transfers

Layer2 systems interact with a base layer using different scaling designs. Cross-layer transfers may involve bridges, challenge periods, batching or different confirmation rules, so arrival times cannot be guaranteed.

Bridge Risk

Official and third-party bridges may differ in operators, fees, contracts and supported assets. Before use, verify the source, destination network, asset type and transaction path, and understand smart-contract and service-provider risk.

Security reminder: Never disclose recovery phrases, private keys or verification codes. Verify network, address and amount before transfers, and understand risks before using third-party DApps, contracts, bridges or staking services.
