Deposit token vs stablecoin

Deposit token vs stablecoin

Same dollar, two designs. The difference is where the dollar is while the token exists.

The two paths

Stablecoin: where the dollar goes.
Deposit token: where the dollar goes.

Side by side

Where they differ.

Each dimension scored from the institution's side: green serves it, red works against it, amber depends.

What the holder owns
StablecoinNo: An IOU from a private issuer, backed by a reserve
Fiat-on-ChainYes: A bank deposit in programmable record form
Where the dollar is in transit
StablecoinNo: A Treasury bill or cash at a custodian, owned by the issuer
Fiat-on-ChainYes: Central bank money, moving between banks' settlement accounts
Credit risk
StablecoinNo: On the issuer and its custodian; uninsured
Fiat-on-ChainYes: On the holder's own bank, within its existing insurance and supervision
How the records are kept equal
StablecoinNo: A monthly attestation; a reserve data feed
Fiat-on-ChainYes: A proof every cycle; issuance halts automatically if it is late or wrong
Finality
StablecoinPartial: On-chain for the token; a bank wire to cash out
Fiat-on-ChainYes: Deterministic, in central bank money, at any hour
Reach
StablecoinYes: Anyone with a wallet, including the unbanked
Fiat-on-ChainPartial: Account-holders at member institutions, under their rules
Reserve, oracle, bridge
StablecoinNo: All three
Fiat-on-ChainYes: None
Dimensions in the institution's favour
Stablecoin: 1 of 7
Fiat-on-Chain: 6 of 7

The verdict

Where the money already sits in a bank, the stablecoin adds layers; the deposit token removes them.

A stablecoin exists to move regulated money outside the institution that holds it. If the institutions are already on the network, that step has no function — and every component built to police it (the reserve, the attestation, the data feed, the redemption queue) has no function either.

What we do not claim

  • Stablecoins persist where bank access is absent — the unbanked and non-bank on-chain markets — and we make no claim there.
  • External prices still need a signed source; only the reserve oracle disappears.
  • Deposit status, insurance and classification are confirmed by counsel per jurisdiction.
