USDB
Blast USDB
Blast's native auto-yielding stable — bridged DAI under the hood, paying T-bill yield via the chain's default-yield model.
USDB is what bridged stables become inside Blast. Yield is delivered via the chain's bridged-stable wrapper around T-bill exposure. Bridge withdrawal returns USDB back to its underlying.
