SEDRAThe Bridge
Swap between SDR and wSDR.
SDR on the Sedra chain, wSDR on Polygon, one and the same value. Wrap and unwrap at 1:1, with every wSDR backed by SDR in a public reserve.

An honest word on trust. Sedra is a UTXO chain with no smart-contract layer, so a fully "trustless" bridge is not achievable here, and we will not claim one. This is a transparent, multi-signature-attested bridge with public Proof of Reserve: independent signers confirm each release, the reserve is on-chain and checkable by anyone, and the signer set decentralizes over time.
Backed 1:1
Every wSDR is a claim on one SDR held in reserve. Check it live on the Proof of Reserve page.
No single key
Releases are approved by a multi-signature Safe, not one operator. No single key can mint or move the reserve.
Caps and pause
The wSDR contract enforces per-transaction and daily limits plus an emergency pause on the automated path.
