Verified Fact Boundary
1. Circle documentation lists specific chains and API chain codes for supported USDC and EURC flows. 2. Circle supported-chain documentation warns against sending unsupported tokens or unsupported appchain transfers to Circle Mint addresses. 3. Circle's multichain USDC page describes USDC availability across multiple networks. 4. Lido documentation describes integration considerations for stETH and wrapped stETH. 5. BIS commentary distinguishes stablecoins and tokenised deposits by monetary properties such as singleness, interoperability and integrity. 6. A route checklist should not treat native USDC support, bridged USDC, stETH and wstETH as interchangeable assets.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Asset identity | USDC, bridged USDC, stETH and wstETH are separate assets or representations | write the exact asset and contract or chain label before transfer | wallet labels that hide bridge or wrapper detail |
| Supported chain | Circle support depends on chain and currency pairing | compare the source and destination chain against official supported-chain tables | new network launches not reflected in a cached UI |
| Wrapper semantics | wstETH changes representation while preserving an underlying staking exposure concept | separate wrapper mechanics from redemption or liquidity assumptions | secondary-market liquidity at the time of exit |
| Credit boundary | unsupported deposits may not credit even when a transaction exists onchain | stop before sending unsupported tokens to hosted addresses | support recovery possibility for a specific private incident |
| Monetary function | stablecoins and tokenised deposit models differ in settlement and trust design | avoid describing all tokenized value as the same money-like instrument | local regulatory classification |
| Evidence record | route evidence should include source, chain, asset, destination and stop rule | do not expose balances, private addresses or support case data | whether the destination entity accepts the asset |
| Stop rule | pause when asset identity or supported chain cannot be verified | use a non-production or tiny test only after support is confirmed | network congestion or contract pause state |

Control Notes
1. Asset identity
Asset identity is the decision point where public documentation must become an operating rule. In this package, it means USDC, bridged USDC, stETH and wstETH are separate assets or representations. The practical action is to write the exact asset and contract or chain label before transfer. The unresolved edge is wallet labels that hide bridge or wrapper detail, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, recovery guarantee, price implication, settlement guarantee or platform ranking.
2. Supported chain
Supported chain is the decision point where public documentation must become an operating rule. In this package, it means Circle support depends on chain and currency pairing. The practical action is to compare the source and destination chain against official supported-chain tables. The unresolved edge is new network launches not reflected in a cached UI, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, recovery guarantee, price implication, settlement guarantee or platform ranking.
The operating test is also narrow. A public page can prove public wording.
3. Wrapper semantics
Wrapper semantics is the decision point where public documentation must become an operating rule. In this package, it means wstETH changes representation while preserving an underlying staking exposure concept. The practical action is to separate wrapper mechanics from redemption or liquidity assumptions. The unresolved edge is secondary-market liquidity at the time of exit, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, recovery guarantee, price implication, settlement guarantee or platform ranking.
The operating test is also narrow. A public page can prove public wording.
4. Credit boundary
Credit boundary is the decision point where public documentation must become an operating rule. In this package, it means unsupported deposits may not credit even when a transaction exists onchain. The practical action is to stop before sending unsupported tokens to hosted addresses. The unresolved edge is support recovery possibility for a specific private incident, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, recovery guarantee, price implication, settlement guarantee or platform ranking.
The operating test is also narrow. A public page can prove public wording.
5. Monetary function
Monetary function is the decision point where public documentation must become an operating rule. In this package, it means stablecoins and tokenised deposit models differ in settlement and trust design. The practical action is to avoid describing all tokenized value as the same money-like instrument. The unresolved edge is local regulatory classification, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, recovery guarantee, price implication, settlement guarantee or platform ranking.
The operating test is also narrow. A public page can prove public wording.
6. Evidence record
Evidence record is the decision point where public documentation must become an operating rule. In this package, it means route evidence should include source, chain, asset, destination and stop rule. The practical action is to do not expose balances, private addresses or support case data. The unresolved edge is whether the destination entity accepts the asset, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, recovery guarantee, price implication, settlement guarantee or platform ranking.
The operating test is also narrow. A public page can prove public wording.
7. Stop rule
Stop rule is the decision point where public documentation must become an operating rule. In this package, it means pause when asset identity or supported chain cannot be verified. The practical action is to use a non-production or tiny test only after support is confirmed. The unresolved edge is network congestion or contract pause state, so the article keeps that edge explicit instead of turning it into a reward claim, licensing claim, approval claim, recovery guarantee, price implication, settlement guarantee or platform ranking.
The operating test is also narrow. A public page can prove public wording.

Practical Takeaway
USDC chain support and liquid-staking token wrappers solve different asset-route problems. Circle documentation lists supported chains and warns that unsupported tokens or unsupported appchain transfers may not be credited, while Lido documentation explains stETH and wrapped stETH integration considerations. The decision outcome is to identify whether the user is moving native supported USDC, bridged or appchain USDC, stETH, wstETH or another wrapped asset before treating a route as redeemable, credited or operationally equivalent. The article stops at the evidence boundary. It helps the reader decide what to inspect next without converting public documentation into a promise that a private account, wallet, callback, policy framework, settlement route or liquidity position will work under every future condition.
