Which chains does Sweepster support?
Sweepster supports 11 EVM mainnets today, all reachable through the same gasless flow — sign once, and Sweepster moves any ERC-20 from any of these chains to any wallet on any supported chain. Every chain below is EIP-7702-capable, which is the delivery mechanism the product uses end-to-end.

Adding new chains
A chain is added once it has EIP-7702 support, a Uniswap V3 deployment for token-risk screening, and a supported bridge for cross-chain delivery. Token support on every listed chain is gated by Sweepster's Token Risk Engine — any ERC-20 is eligible, not just a static allowlist.
