EVM swap: the same trade, on the Ethereum chains
One WalletConnect session reaches the major EVM chains — Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, BSC and Monad — with the same flat fee and the same scan-before-you-buy discipline.
The EVM swap brings the same trade shape to the Ethereum-compatible world: pick the chain, pick the tokens, sign once. The connector is WalletConnect — one session across every supported chain — and it shares its state with the EVM bridge page, so connecting on either surface restores the identical session on the other.
The chains it covers
Ethereum mainnet, Base, Arbitrum, Optimism, Polygon, Avalanche, BSC and Monad — the set the server can actually quote and route on, which is the only honest way to publish a chain list. Deep links carry the chain and the token: /evm?chain=&buy= preloads the pair, which is what the scanner's result cards point at when a flagged token lives on an EVM chain.
The same discipline as the Solana side
Two things carry over unchanged. The fee: flat 1%, shown before signing, split 50/50 with a referrer when one exists. And the pairing: a fresh wallet connection runs the sanctions screen before it can trade — the same Chainalysis-backed check the Solana surfaces run — and the scanner reads EVM contracts with the same mint/freeze/holder logic it applies at home. A new chain doesn't change the read.
The EVM-specific trap: approvals. EVM tokens ask for spending allowances that persist after the trade — a malicious approval is the classic drain. Know what you're signing, and review stale allowances: token approval drains and revoking is the guide.
Swap on the EVM chains, one session
WalletConnect covers every supported chain at once — flat 1% fee, sanctions-screened connect, scan before you buy.
Frequently asked
Which chains does the EVM swap support?
Ethereum mainnet, Base, Arbitrum, Optimism, Polygon, Avalanche, BSC and Monad — the set the server can actually quote and route, connected through a single WalletConnect session.
Do I need a separate connection per chain?
No — one WalletConnect session covers every supported chain, and the same connector is shared with the EVM bridge page, so connecting once restores the session on both surfaces.
What does the EVM swap cost?
The same flat 1% fee as the Solana side, shown before you sign — half of it goes to a referrer on trades that arrive through a referral link.
Does the token scanner work on EVM contracts?
Yes — the scan reads EVM contracts with the same authority/holder/liquidity logic it applies on Solana, and flagged results deep-link straight into the EVM swap with the pair preloaded.
