Cross-Chain Transfer Protocol: native burn and mint for USDC
Circle CCTP. Circle.
CCTP burns USDC on a source chain and mints USDC on a destination chain when Circle's attestation service signs the burn. The attestation is the trust assumption.
A reading of the project's public design document. Not a copy, not a benchmark, and not an offer.

01 Claim ledger
What the paper is allowed to say
Each row is a sentence already in the study. The status is the same on every row: a model claim, not a live measurement.
Claim 01 · Paper model
The defect
Native burn-and-mint is not a lock in a third-party bridge. It is also not a claim that the attestation is a light client.
Claim 02 · Paper model
The proposal
CCTP burns USDC on a source chain and mints USDC on a destination chain when Circle's attestation service signs the burn. The attestation is the trust assumption.
Claim 03 · Paper model
The mechanism
A burn on the source is the event. Circle's attestation says the burn happened. The destination minter relies on that attestation.
Claim 04 · Paper model
The bound
This note states no supply of USDC and no fee.
02 Three cuts
Observation, model, falsifier
A desk does not stop at the summary. Each claim is cut three ways, using only this study's own assumptions and checks. Nothing here is a new figure.
01 The defect
Observation
What the study says
Native burn-and-mint is not a lock in a third-party bridge. It is also not a claim that the attestation is a light client.
Model
What has to hold
You are reading Circle's CCTP documents. A wrapped USDC from another bridge is a different asset.
Falsifier
What would retire it
Who signs the attestation the destination checks?
02 The proposal

CCTP burns USDC on a source chain and mints USDC on a destination chain when Circle's attestation service signs the burn. The attestation is the trust assumption.

04 The bound
Observation
What the study says
This note states no supply of USDC and no fee.
Model
What has to hold
No price, supply, yield, or adoption figure is added by this desk.

What would retire it
Who signs the attestation the destination checks?
03 Sequence
One action, as an operating tape
- 01A burn on the source is the event. Circle's attestation says the burn happened. The destination minter relies on that attestation.
- 02USDC on each chain is still a Circle liability under Circle's own terms. CCTP moves the ledger location. It does not change who the issuer is.
- 03Fast or standard transfer, if the docs distinguish them, are different finality assumptions and have to be cited separately.
04 Load-bearing
The argument, and where a pitch drops it
What the name has to mean
The cut
CCTP burns USDC on a source chain and mints USDC on a destination chain when Circle's attestation service signs the burn. The attestation is the trust assumption.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
An attestation service is a trusted signer. Write it that way.
What actually moves
The cut
USDC on each chain is still a Circle liability under Circle's own terms. CCTP moves the ledger location. It does not change who the issuer is.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
It does not say CCTP is available on any particular chain. The docs list changes.
What a later deployment may change
The cut
Fast or standard transfer, if the docs distinguish them, are different finality assumptions and have to be cited separately.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
A later client, parameter or reward formula is a different object from this paragraph.
05 Register
What has to be true
Model · Not re-measured
You are reading Circle's CCTP documents. A wrapped USDC from another bridge is a different asset.
Model · Not re-measured
The document is the one at the source URL. A marketing page with the same brand is not this text.
Model · Not re-measured
No price, supply, yield, or adoption figure is added by this desk.
06 Divergence
What happened after the paper
An attestation service is a trusted signer. Write it that way.
A later client, parameter set, or reward formula is a different object. Cite this paper for the mechanism. Cite a primary release for the network. This desk has not re-run the proof.

08 Anatomy
The paper, in the order a builder needs
The problem it names
Native burn-and-mint is not a lock in a third-party bridge. It is also not a claim that the attestation is a light client.
What the design proposes
- A burn on the source is the event. Circle's attestation says the burn happened. The destination minter relies on that attestation.
- USDC on each chain is still a Circle liability under Circle's own terms. CCTP moves the ledger location. It does not change who the issuer is.
- Fast or standard transfer, if the docs distinguish them, are different finality assumptions and have to be cited separately.
How the mechanism is specified
- A burn on the source is the event. Circle's attestation says the burn happened. The destination minter relies on that attestation.
- USDC on each chain is still a Circle liability under Circle's own terms. CCTP moves the ledger location. It does not change who the issuer is.
- Fast or standard transfer, if the docs distinguish them, are different finality assumptions and have to be cited separately.
What this page does not treat as proven
- This note states no supply of USDC and no fee.
- It does not say CCTP is available on any particular chain. The docs list changes.
- An attestation service is a trusted signer. Write it that way.
Why the desk still reads it
CCTP burns USDC on a source chain and mints USDC on a destination chain when Circle's attestation service signs the burn. The attestation is the trust assumption.
09 Lexicon
Terms, opened into the record
- Burn and mint
- Destroying the token on one chain and creating it on another, rather than wrapping a locked balance.
- Attestation service
- The signer the destination trusts to say the burn occurred.
