Glossary
Key terms to understand Twin's stablecoins and their infrastructure.
Stablecoin
A crypto token designed to hold a stable value against a reference asset. Twin's stablecoins track local LATAM currencies (Argentine peso, real, etc.), not the US dollar.
Peg
The target value relationship between the token and its reference. Twin tokens aim for a 1:1 peg to their local currency.
RWA (Real World Asset)
A real-world asset tokenized on-chain. The fiat currencies backed by Twin are a type of RWA.
Mint
Creation of new tokens. A user deposits the corresponding asset and receives the equivalent stablecoin. See mint/redeem in the app.
Redeem
The inverse of mint: the user hands back the stablecoin and receives the underlying asset. Reduces circulation.
Bridge
A mechanism to move a token between different networks. Twin's bridge uses the burn & mint model over LayerZero. See Bridge.
Burn & mint
A bridge model where tokens are burned on the source network and minted on the destination network, preserving total supply. No liquidity pools or locked funds.
OFT (Omnichain Fungible Token)
LayerZero's standard for fungible tokens that exist natively across several networks with unified supply. Twin's bridge adapters implement OFT.
LayerZero
Cross-chain messaging protocol that carries the transfer instructions between networks. Twin uses LayerZero V2.
Adapter
A contract (one per token and network) that runs the bridge send/quoteSend: burns on the source, mints on the destination. See the table in Bridge.
EID (Endpoint ID)
The identifier LayerZero uses to address a network. Different from the EVM chain ID. See Supported chains.
Chain ID
Numeric identifier of an EVM network (Base = 8453, Polygon = 137, Arbitrum = 42161, Ethereum = 1).
ERC-20
The standard for fungible tokens on EVM. All Twin tokens are 18-decimal ERC-20s.
Decimals
The number of decimals a token uses. Twin tokens use 18; USDC/USDT use 6.
Oracle
A contract that publishes each Twin token's reference price on-chain, used by the platform and liquidity.
Proof of Reserves
Verifiable demonstration that a token's circulation is backed ≥ 1:1 by reserves. See Proof of reserves.
Circulation (total supply)
The total amount of a token in existence, summed across all networks. Public and auditable on-chain.
Settlement
The asset used to pay for an operation (typically USDC or USDT) when minting or redeeming.
On/off-ramp
A bridge between traditional fiat money and crypto: an on-ramp converts fiat → token, an off-ramp token → fiat. (Documentation coming soon.)
