El Salvador Strategic Bitcoin Reserve

National Bitcoin Office of El Salvador (ONBTC)

Scored from ONBTC treasury catalogue, bitcoin.gob.sv (live), 20 of 20 published addresses read. Policy announced 29 August 2025: up to 500 BTC per address, no reuse, all addresses catalogued. See the live attestation at /attest/el-salvador. Snapshot .

By exposure class

Practical risk

An attacker must recover each key separately. 0 exposed keys hold 10 BTC or more, 0 BTC in total; that is the part worth attacking first, and the part to sweep to fresh keys first.

Largest exposed keys

Disclosure freshness

Live endpoint. The holder's endpoint was read 55 days ago.

Custody, as observed on-chain

Of the 7,791 BTC in the 20 addresses read, 0% is spent by a single key (indistinguishable from MPC on-chain), 0% through a multisig script, and 100% has never spent, so its control is not yet visible.

Read from 20 of 20 published addresses, holding 7,791 BTC, on 2026-09-30.

Repeated nonces

1,665 signatures from 2 keys across 2 addresses were checked and no nonce was repeated. For 1 busy address only the most recent transactions were read.

What it would take to move the exposed balance

1 unspent outputs in 1 transaction, about 0.0000 BTC in fees at the one-hour rate (about $0 at today’s price), using well under one percent of a day’s block space.

Each of the 1 unspent outputs is spent once into one fresh output of the same script family, in transactions of up to 400 inputs. Fee rates are mempool.space's recommendations at 2026-09-30T22:10:56.393Z. Signing ceremonies, custody procedures and withdrawal queues are not included and usually dominate.
