Episode notes
On-Chain Letters Of Credit
- Anvil turns on-chain collateral into transferable letters of credit that act like blockchain IOUs.
- This creates a transparent, fully collateralized buy-now-pay-later flow without custodial risk.
Using Anvil To Reserve A Consensus Sponsorship
- Tyler has attended every Consensus since 2015 and used Anvil to reserve a sponsorship without selling crypto.
- He demonstrated Anvil by letting sponsors reserve now and pay months later while keeping custody of assets.
Keep Conditions Off-Chain
- Avoid complex on-chain conditional logic and let recipients cash letters of credit freely.
- Keep arbitration off-chain between buyer and seller to preserve simplicity and enforceability.
