What is Bondrail

Bondrail lets businesses create a revenue account with BondrailFactory.createAccount and issue a bond with createBond. Investors deposit the account's asset and receive ERC-20 claims. After activation, an agreed share of connected revenue goes to the bond up to its effective cap; capital is released in stages. Repayment depends on revenue, not promised interest or guaranteed principal.

Native projects route fees through BondrailAccount.collect / settleOut. Paid APIs can use account.settle to verify an EIP-3009 payer and book/split immediately. sweep books plain transfers. Each route builds history before or during a bond.

• Native templates: deployNative deploys and binds approved template code without individual review. Custom contracts inheriting BondrailEarner need individual approval before raising.
• Performance triggers: checkTrigger can raise the investor share when booked revenue falls below the agreed floor; a later check can restore it. Payments use the last checked share.
• Credit vault: BondrailVault pools investments with carried-cost valuation, separate entry/exit prices, seven-day income vesting and exits limited to idle cash.
• Credit profiles: onchainProfile exposes state and coverage; attestedProfile adds a separately trusted assessment. SDK credit-line and yield estimates are advisory.

Claims can transfer after Funding. BondrailBond.redeem burns the position for current pool backing, giving up future receipts; the last claim waits for Closed. Kuru exits depend on a listed market and liquidity.
