Transaction Size Limit

The maximum serialized size of a Solana transaction: 1,232 bytes, matching the IPv6 minimum MTU to ensure single-packet transmission. This limit constrains the number of accounts, instructions, and data per transaction. Address lookup tables (v0 transactions) help fit more accounts within this limit.

Estas ramas muestran qué conceptos toca este término directamente y qué existe una capa más allá de ellos.

Rama

Transacción

An atomic unit of execution containing one or more instructions, a recent blockhash, and one or more signatures. All instructions in a transaction execute sequentially and atomically—if any instruction fails, the entire transaction reverts. Transactions have a 1,232-byte size limit (matching IPv6 MTU) and a default 200,000 CU budget.

Rama

Address Lookup Table (ALT)

An on-chain account that stores up to 256 pubkeys, enabling v0 transactions to reference accounts by 1-byte index instead of full 32-byte pubkeys. ALTs dramatically reduce transaction size when interacting with many accounts (e.g., DEX routing). ALTs must be created and populated in advance; entries become active after a slot delay.

Rama

Versioned Transaction

A transaction format introduced with v0 that supports address lookup tables. Legacy transactions include all pubkeys inline (limited to ~35 accounts); v0 transactions reference ALTs to include up to 256 accounts while staying within the 1,232-byte limit. The version byte (0) precedes the message.

Modelo de Programación

Unidades de Cómputo (CU)

A measure of computational resources consumed by transaction execution, analogous to gas on Ethereum. Each BPF instruction costs CU; syscalls have predefined CU costs (e.g., SHA-256: 85 CU base + per-byte). Default per-instruction limit is 200,000 CU; max per-transaction is 1,400,000 CU. Priority fee cost = CU price × CU consumed.

Modelo de Programacióntransaction-id

Transaction ID

The first signature in a transaction, which uniquely identifies it on the network. Since each transaction has a unique combination of signers and a recent blockhash, the first signer's Ed25519 signature over the transaction message serves as a globally unique identifier. Transaction IDs are displayed as Base58-encoded 64-byte strings and used for lookups via getTransaction and getSignatureStatuses.

Modelo de Programacióntransaction-mortality

Transaction Mortality

The limited lifespan of a Solana transaction determined by its referenced blockhash. A transaction's blockhash must correspond to a block within the last 150 slots (~60-90 seconds) or the transaction is rejected as expired. This mechanism prevents replay attacks and bounds the time validators must track transaction deduplication. Durable nonces bypass mortality for use cases requiring long-lived transactions.

Modelo de Programacióntransaction-simulation

Transaction Simulation

The broader developer workflow of dry-running a Solana transaction before broadcast to inspect logs, catch runtime failures, estimate compute usage, and verify account assumptions. Transaction simulation can happen through the simulateTransaction RPC method, preflight checks inside sendTransaction, or specialized bundle and bot pipelines that repeatedly simulate against fresh state before deciding to submit.

Modelo de Programación

Cuenta

The fundamental data storage unit on Solana. Every piece of state is stored in an account identified by a 32-byte public key. Accounts hold a lamport balance, an owner program, a data byte array (up to 10MB), and an executable flag. Only the owning program can modify an account's data, but anyone can credit lamports to it.

Modelo de Programación

Programa

Executable code deployed on-chain, equivalent to a smart contract on other blockchains. Programs are stateless—they store no data themselves but read/write data in separate accounts they own. Programs are compiled to SBF bytecode and loaded via the BPF Loader. Every program has a unique Program ID (its account's public key).

Modelo de Programación

Instrucción

A single operation within a transaction that invokes a program. An instruction specifies: (1) the program ID to call, (2) an array of account metas (pubkey, is_signer, is_writable), and (3) an opaque data byte array. Programs decode the instruction data to determine which operation to perform.
