sw4p

sw4p is the cross-chain bridge powering the Render Network Protocol’s multi-chain settlement. It uses Circle’s CCTP V2 (Cross-Chain Transfer Protocol) to move USDC across chains non-custodially.

How It Works

  1. Burn: USDC is burned on the source chain.
  2. Attest: Circle’s attestation service verifies the burn.
  3. Mint: USDC is minted on the destination chain and delivered to the recipient.
No wrapped tokens. No liquidity pools. The USDC on the destination chain is native Circle USDC.

Security

sw4p has undergone 5 independent security audits:

EVM ContractsPassed

Findings: 0 critical, 0 high severity. All medium and low findings resolved.

​
Integration

sw4p is integrated throughout the Render Network Protocol:
  • AGG: Uses sw4p for cross-chain payment routing.
  • Hyperlink: Payment links resolve cross-chain through sw4p.
Supported Asset: sw4p bridges USDC only (via CCTP V2). The $555 token is a Solana SPL token and is not bridged by sw4p.
