wstGBP (Wren Staked tGBP) is a non-custodial, non-rebasing ERC-20 wrapper around tGBP, a pound sterling stablecoin issued by BCP Technologies, an FCA-registered UK cryptoasset business, and backed 1:1 by sterling reserves.

Users mint wstGBP by depositing tGBP and can redeem on demand at the published on-chain exchange rate, keeping self-custody throughout. Balances never rebase, so wallets, treasuries, and DeFi integrations track one exchange rate instead of shifting balances.

1 wstGBP equalled 1 tGBP at deployment; value accrues into the wstGBP-to-tGBP exchange rate through periodic NAV updates. wstGBP is issued by Wren Spire (BVI) Ltd, an Arb Capital company.
