Accepting a payment is settling it

This lesson opens with Silvergate Bank and the Silvergate Exchange Network, March 2023.

What happened

Silvergate was a small California bank that had become critical plumbing for the crypto industry through the Silvergate Exchange Network, the SEN, which let exchanges, funds and trading firms move US dollars between one another instantly and around the clock. That is the thing real payments need: not just a claim, but final, usable dollars in the recipient's account, at any hour. After FTX collapsed in late 2022, a run pulled roughly eight billion dollars in deposits from Silvergate; the bank sold assets at a loss to meet the outflow, shut the SEN on 3 March 2023, and on 8 March 2023 announced it would wind down and voluntarily liquidate. It liquidated in an orderly way and depositors were made whole, which is why the direct loss here is zero, but the rail was gone: firms that had built their settlement on the SEN suddenly had no instant path to move dollars, especially outside banking hours. The dollars survived; the settlement rail did not, and a payment system is only as good as the rail that finishes its payments.

The decision point

Accepting a payment and settling a payment are two different events, and only the second one is money. A payment is settled when it becomes final, usable funds in the recipient's control, which for dollars means a rail, a bank, a network, a settlement system, carrying the value from payer to payee and making it final. Silvergate's SEN was that rail for much of the industry: instant, around-the-clock dollar movement between members. When it vanished, nothing about the dollars changed, but the ability to settle in them instantly did, because settlement is not a property of the money, it is a service provided by a rail that can fail. So the decision anyone building on payments makes is to treat the settlement rail as a dependency to be understood and diversified, not as permanent infrastructure that will always be there, because a payment you cannot settle is not a payment yet, and the rail that settles it is a company, a network or a bank that can shut its doors, as Silvergate did, on a weekend, taking the instant settlement everyone relied on with it.

Orientation and Year One are open: anyone can read them without an account. From Year Two onward the lessons are for enrolled learners, because progress through the later years only means anything if it is tracked against a record.

It is free. We do not sell the list and there is nothing to buy at the end of it.
