Monipay Glossary | Terminology for Users, Merchants and Developers

Glossary

AES-256-GCM | Authenticated symmetric encryption with a 256-bit key. Monipay encrypts every user's private key with AES-256-GCM, keyed by a PBKDF2 derivation of the user's PIN.

AlphaUSD (αUSD) | Tempo's primary stablecoin. 18 decimals. TIP-20 standard. Contract 0x20c0000000000000000000000000000000000001.

Atomic split | The single-transaction transfer pattern Monipay's router contracts use to send 99% of a payment to the recipient and 1% to the platform treasury without any intermediate state.

Base | Coinbase's Ethereum L2. Monipay's home chain. Token: native USDC, 6 decimals.

Base58 | Solana's canonical address encoding. Case-sensitive, no normalization.

BEP-20 | BSC's token standard, broadly ERC-20-compatible. BSC USDT is BEP-20 with 18 decimals.

Builder code (ERC-8021) | On-chain attribution suffix that lets a builder count originated transactions. Monipay's Base builder code is bc_qt9yxo1d.

Celo | Opera's target network, running Celo mainnet. Support for USDT via MiniPay deep links.

Ed25519 | Solana's signing curve. Used for Solana keypairs.

EIP-712 | Ethereum's typed structured-data signing standard. Monipay's EVM routers verify EIP-712 signatures to authorise meta-transactions.

EIP-2718 type 0x76 | Tempo's native transaction envelope type. Supports feePayer sponsorship, 2D nonces, and atomic batch calls as first-class fields.

executor wallet | MoniBot's hot wallet that submits social-payment transactions and pays gas. Per-chain, monitored, refilled on low-balance alerts.

fee-on-top | MoniBot's social-payment fee model. Sender pays amount + 2% (for MagicPay), recipient receives the full amount. Contrast with the in-app fee-split model.

feePayer | A Solana and Tempo transaction field naming a non-sender account that pays the fee. The foundation of Monipay's gasless UX on those chains.

Hammer | Monipay's product philosophy. A tool you own and walk away with, not a service you depend on. See the Walkaway Test.

Ink | Kraken's Ethereum L2 network. Supported token is USDT0, an omnichain USDT variant.

IOURegistry | On-chain registry that backs MagicPay claims. Holds escrowed funds for unaddressed recipients until they prove control of the linked social handle.

MagicPay | A claim link issued when a MoniBot recipient has no linked MoniTag. Backed by the on-chain IOURegistry. Recipient redeems by signing up and proving handle ownership.

MagicPay fee | The platform fee of 2% charged for social payments and tipping via MoniBot/MagicPay.

MiniPay | Opera's mobile wallet on Celo. Monipay runs as a mini-app inside MiniPay.

MiniPay deep link | URI scheme monipay:// for launching payments inside Opera MiniPay browser.

MoniBot | Monipay's autonomous AI agent for social payments on Twitter/X, Discord, and Telegram.

Monipay | The product. A gasless, non-custodial, multi-chain stablecoin wallet and payment platform.

MoniTag™ | Your permanent username on Monipay. Lowercase m, uppercase T, ™ on first use.

paymaster | A relayer that pays gas on a user's behalf in exchange for the user's signature on an off-chain typed-data message.

PBKDF2 | Password-Based Key Derivation Function. Monipay uses PBKDF2 with a high iteration count to derive an AES key from the user's PIN.

RLS | Row Level Security. Supabase's database access control. Monipay's tables are deny-all by default with explicit policies per access path.

secp256k1 | Ethereum's signing curve. Used for EVM keypairs (Base, BSC, Celo, Ink).

Smart Feedback | MoniBot's optional AI-evaluated reply quality gate for airdrop and grant campaigns. Powered by Gemini 2.0-flash.

Soft delete | Monipay account deletion sets profiles.status = 'deactivated' rather than dropping rows. Data is retained for legal compliance. Re-import is blocked.

TIP-20 | Tempo's stablecoin standard. ERC-20-like, with on-chain transfer memos and delegated-transfer semantics for sponsorship.

Two-dimensional (2D) nonce | Tempo's (nonceKey, nonce) pair that allows parallel-safe concurrent transactions without single-account nonce contention.

USDC | Circle's regulated US-dollar stablecoin. Native on Base (6 dec) and available as SPL on Solana (6 dec).

USDT | Tether's US-dollar stablecoin. Native on BSC as BEP-20 (18 decimals) and Celo (6 decimals), and as USDT0 omnichain variant on Ink.

Walkaway Test | Monipay's resilience principle: if Monipay disappeared tomorrow, you could still spend the funds in your wallet from any compatible wallet. Non-negotiable.

worker bot | Per-platform MoniBot service that polls the social platform, parses commands, and submits on-chain transactions via the chain-specific MoniBotRouter.
