Glossary

Products & assets

Term	Meaning
Stablebond	A tokenized, yield-bearing sovereign bond (e.g. CETES) — it earns the yield of the underlying government debt while you hold it on-chain.
Stablecoin	A token pegged to a fiat currency, such as USDC.

Stablebonds

Stablebonds are yield-bearing — they accrue the yield of the underlying sovereign debt while you hold them.

Token addresses

Each stablebond is deployed on multiple chains, each with its own mint (Solana), asset issuer (Stellar), or token contract (EVM). The addresses below are pulled live and link to each chain’s block explorer. Use these to verify a token, add a trustline, or import the asset — but when quoting or building orders, always use the identifier from GET /ramp/assets rather than hardcoding (sandbox identifiers differ from these production ones).

Transaction types

Term	Meaning
Onramp	Buying tokens with fiat (the customer pays MXN and receives tokens).
Offramp	Selling tokens for fiat (the customer sends tokens and receives MXN).
Swap	Exchanging one token for another.
Quote	Time-bound pricing for a transaction. Quotes expire after 2 minutes.
Order	An onramp or offramp transaction created from a quote.

Fiat & banking (Mexico)

Term	Meaning
MXN	Mexican peso.
SPEI	Mexico’s real-time interbank electronic transfer system.
CLABE	The 18-digit standardized Mexican bank account number used for SPEI transfers.
depositClabe	The CLABE a customer deposits MXN into to fund an onramp order.
RFC	Mexican taxpayer ID (Registro Federal de Contribuyentes). Sandbox uses placeholder RFCs — see the Sandbox Reference.

Fiat & banking (Brazil)

Term	Meaning
BRL	Brazilian real — the fiat currency for Brazil ramps.
Pix	Brazil’s instant payment system, operated by the Central Bank of Brazil. The Brazilian equivalent of SPEI.
Pix key (`pixKey`)	The identifier a Pix payment is sent to or received from. Its kind is given by `pixKeyType`.
Pix key type (`pixKeyType`)	The kind of Pix key — commonly a CPF, CNPJ, email, phone number, or a random (EVP) key.

KYC	Know Your Customer — identity verification for an individual (personal customer).
KYB	Know Your Business — verification of a business entity, such as your organization for production access.

On-chain

Term	Meaning
Public key / wallet	A blockchain wallet address registered to a customer.
Proxy account	Etherfuse’s internal record linking a customer’s wallet and identity. `Proxy account not found` means the supplied IDs don’t match onboarding.
Trustline	(Stellar) Authorization a wallet must establish before it can hold a given asset. Handled automatically for Stellar onramps.
XDR	(Stellar) The encoded transaction format a user signs (e.g. the `stellarClaimTransaction`).
Claimable balance	(Stellar) A pending balance the recipient claims; used for first-time wallet onramps.

Stellar anchor	A bridge between the Stellar network and traditional fiat rails, defined by Stellar Ecosystem Proposals (SEPs). Etherfuse acts as an anchor for Stellar offramps. Learn more ↗
Anchor mode	(Stellar offramps) Setting `useAnchor: true` makes Etherfuse return the anchor destination account and memo (SEP-24) instead of a pre-signed `burnTransaction` — you build and submit the payment yourself. See Anchor Mode.
