Glossary OS

Plain meaning

Start with the shortest useful explanation before going deeper.

The simpler of the two Solana Pay sub-protocols, encoding a static SOL or SPL token payment request as a URI in the format solana:<recipient>?amount=<value>&spl-token=<mint>&label=<label>&memo=<memo>. Transfer Request URIs are fully self-contained and require no server interaction — wallets parse the URI and construct the system program transfer or SPL token transfer instruction locally, making them ideal for fixed-price invoices and tip links.

Mental model

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.

Think of it as a building block that connects one definition to the larger Solana system around it.

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

RPCs, validators, snapshots, indexing, and network plumbing.

Why builders care

Turn the term from vocabulary into something operational for product and engineering work.

This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

Branch

Solana Pay

An open payment standard and SDK that defines URI schemes and protocol flows for requesting SOL or SPL token transfers and for constructing and returning partially-built transactions from merchant backends to user wallets. It comprises two sub-protocols — Transfer Requests (simple static payment URIs) and Transaction Requests (dynamic server-signed transaction fetching) — and enables point-of-sale payments, loyalty programs, and interactive commerce experiences using QR codes or deeplinks.

Triton

A professional Solana infrastructure provider (operating as Triton One) specializing in high-performance dedicated RPC nodes, the Yellowstone gRPC Geyser plugin, and enterprise-grade validator infrastructure. Triton is notable for maintaining and open-sourcing the Yellowstone Dragon's Mouth gRPC streaming stack and for offering bare-metal RPC deployments tuned for MEV, HFT, and latency-sensitive workloads.

Transaction Request (Solana Pay)

A Solana Pay protocol flow in which a QR code or link encodes an HTTPS URL; when scanned, the wallet performs a GET request to discover metadata (label, icon) and then a POST request with the user's public key, receiving a base64-encoded partially-signed transaction that the wallet can inspect, sign, and submit. This dynamic model enables programmable commerce flows such as NFT minting, coupon redemption, and multi-step checkout because the merchant server constructs the transaction at request time rather than encoding it statically.

Open term

Infrastructure

RPC (Remote Procedure Call)

The JSON-RPC 2.0 protocol interface through which clients communicate with Solana nodes to query chain state, submit transactions, and subscribe to events. Solana exposes a rich set of HTTP and WebSocket endpoints (e.g., getAccountInfo, sendTransaction) that abstract direct peer-to-peer network participation, making RPC the primary integration point for wallets, dApps, and indexers.

Infrastructure

RPC Node

A Solana full node that stores ledger state and serves JSON-RPC and WebSocket requests from clients without participating in consensus or voting. RPC nodes must replay every transaction to maintain an accurate account state database, and high-throughput deployments typically run dedicated RPC nodes with large SSDs, high RAM (256 GB+), and high-bandwidth network connections to handle concurrent client load without impacting validator performance.

Infrastructure

RPC Methods

The enumerated JSON-RPC endpoints exposed by Solana nodes, covering account queries (getAccountInfo, getMultipleAccounts, getProgramAccounts), block and transaction retrieval (getBlock, getTransaction), cluster metadata (getEpochInfo, getSlot, getVersion), and transaction submission (sendTransaction, simulateTransaction). Methods accept a Commitment parameter (processed, confirmed, finalized) to control the recency-vs-safety tradeoff of returned data.

Infrastructure

getAccountInfo

An RPC method that returns the complete on-chain state of a single account identified by its base-58 public key, including its lamport balance, owner program, executable flag, rent epoch, and raw data payload encoded as base64 or base58. It is the most fundamental read primitive in Solana development and is called at the specified commitment level, with the data field being null if the account does not exist.
