Coinbase's tokenized stocks trade on Base all weekend, but their price feeds stop at 8 p.m. Friday, New York time. Boundline lets you borrow against them, paid in your own currency, and never be liquidated while Wall Street is closed.
A real Morpho loan on Base, staged near its limit and replayed on a copy of Base mainnet through a 15% weekend drop. Move the time and watch what each side sees.

Health is the lending market's own measure: below 1, anyone can liquidate the loan. Boundline watches the Aerodrome price less 2%, the same price its onchain ShadowGuard uses.
Start, end and amounts come from Boundline's replay of 7 Oct 2026 on a fork of Base mainnet at block 52,295,895: a real Morpho AAPLc position, staged near its limit, taken through a 15% weekend gap. On the lending market alone it was liquidated at the reopen; on Boundline's path it was not. The path between Friday and Sunday is illustrative. Evidence hash 0xa626f099…793c45.
While the feed holds Friday's close, Boundline's markets stop pricing it: no new borrows, no withdrawals, no liquidations. Repaying and adding collateral never stop.
SessionGuard, a Morpho oracle that reads an onchain NYSE calendar and a verdict on every price. It fails closed.
The stock keeps trading on Aerodrome all weekend. Boundline prices your loan there, and when it drifts toward its limit, it repays a little or sells a small slice of collateral before the reopen can hurt you.
ShadowGuard, Morpho's audited pre-liquidation, a funding ladder that ends at the Boundline Reserve, and Cobalt validity transactions that Base includes only while the feed is still frozen.
One tap sends one batch: authorise, add collateral, draw, and swap the USDC into euros on the way out. The euros arrive with the loan.
On Base Sepolia, 0.5 USDC became 0.46 EURCt inside the borrow flow, behind the same session check: 0x9090633c…5b5bd3.
