BLOCKCHAIN LAB BRIEFING · CUSTODY

A Post Says BNY Will Custody the Reserves Behind Ripple's RLUSD

The claim, if it is Ripple's arrangement, is about who holds the assets behind a dollar token. The post that travelled is not the issuer's post.

3 October 2026

All briefings

01

What happened

On 3 October 2026 @beyond_broke posted that Ripple had selected BNY to custody the reserves behind RLUSD, and that one of the largest custody banks was now holding those assets. On this snapshot the post had 71 reposts, 3 quotes, 37 replies, 894 likes and about 25,000 views.

The account is not Ripple and not BNY. The sentence does not link a press release, a trust agreement, or an attestation.

02

Why it matters

Reserve custody is the question that decides what a holder has if the issuer fails. A bank custody relationship is a different object from a token balance, and it is a different object from a tweet that names both.

For a treasury, the useful document is the one that says which entity holds which assets, under which law, and who can give instructions. This post is not that document.

03

The operating layer

If the claim is later confirmed, the operating checks are ordinary: segregation, the right to look through to the assets, the attestation cycle, and what happens to the token if the bank or the issuer stops. None of those appear in the post.

Until they do, a payout or collateral rule should not treat RLUSD as 'held at BNY' on the strength of this note.

04

What is verified

The post is from @beyond_broke on 3 October 2026. It states a custody selection as fact.

This desk has not retrieved a matching statement from Ripple or from BNY in this pass. The claim is unverified here.

05

What is still unclear

Whether a selection has been signed, whether assets have moved, and which RLUSD issuance (which chain, which legal entity) is in scope.

Whether 'custody the reserves' means a trust, a deposit, or a narrower safekeeping mandate.

06

The catch

A bank's name beside a stablecoin is often used as if the token had become a bank deposit. It has not, on this text. Even a true custody appointment leaves the holder with a claim on the issuer's structure, not an account at the bank.

WATCH

What builders should watch

  1. 01A primary statement from Ripple or BNY naming the same arrangement.
  2. 02Which legal entity issues the token the reserves belong to.
  3. 03The attestation, and whether it names the custodian.
  4. 04What a holder can do if either party stops.

BOTTOM LINE

The post names a famous custodian. It does not show the agreement, and a reserve bank is not the same thing as a claim on that bank.
