Anchor.toml Reference

provider (required)

A wallet and cluster that are used for all commands.

Example:

[provider]
cluster = "localnet"                    # The cluster used for all commands.
wallet = "~/.config/solana/id.json"     # The keypair used for all commands.

scripts (required for testing)

Scripts that can be run with anchor run <script>. The test script is executed by anchor test.

Example:

[scripts]
test = "yarn run ts-mocha -p ./tsconfig.json -t 1000000 tests/**/*.ts"

registry

The registry that is used in commands related to verifiable builds (e.g. when pushing a verifiable build with anchor publish).

Example:

[registry]
url = "https://anchor.projectserum.com"

workspace

types

Adds a directory where you want the <idl>.ts file to be copied when running anchor build or anchor idl parse. This is helpful when you want to keep this file in version control, like when using it on the frontend, which will probably not have access to the target directory generated by anchor.

Example:

[workspace]
types = "app/src/idl/"

members

Sets the paths --relative to the Anchor.toml-- to all programs in the local workspace, i.e., the path to the Cargo.toml manifest associated with each program that can be compiled by the anchor CLI. For programs using the standard Anchor workflow, this can be ommitted. For programs not written in Anchor but still want to publish, this should be added.

Example:

[workspace]
members = [
    "programs/*",
    "other_place/my_program"
]

programs

Example:

[programs.localnet]
my_program = "Fg6PaFpoGXkYsidMpWTK6W2BeZ7FEfcYkg476zPFsLnS"

The addresses of the programs in the workspace.

programs.localnet is used during testing on localnet where it's possible to load a program at genesis with the --bpf-program option on solana-test-validator.

test

startup_wait

Increases the time anchor waits for the solana-test-validator to start up. This is, for example, useful if you're cloning (see test.validator.clone) many accounts which increases the validator's startup time.

Example:

[test]
startup_wait = 10000

genesis

Makes commands like anchor test start solana-test-validator with a given program already loaded.

Example

[[test.genesis]]
address = "9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin"
program = "dex.so"


[[test.genesis]]
address = "22Y43yTVxuUkoRKdm9thyRhQ3SdgQS7c7kB6UNCiaczD"
program = "swap.so"

test.validator

These options are passed into the options with the same name in the solana-test-validator cli (see solana-test-validator --help) in commands like anchor test.

[test.validator]
url = "https://api.mainnet-beta.solana.com"     # This is the url of the cluster that accounts are cloned from (See `test.validator.clone`).
warp_slot = 1337                                # Warp the ledger to `warp_slot` after starting the validator.
slots_per_epoch = 5                             # Override the number of slots in an epoch.
rpc_port = 1337                                 # Set JSON RPC on this port, and the next port for the RPC websocket.
limit_ledger_size = 1337                        # Keep this amount of shreds in root slots.
ledger = "test-ledger"                          # Set ledger location.
gossip_port = 1337                              # Gossip port number for the validator.
gossip_host = "127.0.0.1"                       # Gossip DNS name or IP address for the validator to advertise in gossip.
faucet_sol = 1337                               # Give the faucet address this much SOL in genesis.
faucet_port = 1337                              # Enable the faucet on this port.
dynamic_port_range = "1337 - 13337"             # Range to use for dynamically assigned ports.
bind_address = "0.0.0.0"                        # IP address to bind the validator ports.

test.validator.clone

Use this to clone an account from the test.validator.clone.url cluster to the cluster of your test. If address points to a program owned by the "BPF upgradeable loader", anchor (>= 0.23.0) will clone the program data account of the program for you automatically.

Example:

[test.validator]
url = "https://api.mainnet-beta.solana.com"


[[test.validator.clone]]
address = "7NL2qWArf2BbEBBH1vTRZCsoNqFATTddH6h8GkVvrLpG"
[[test.validator.clone]]
address = "2RaN5auQwMdg5efgCaVqpETBV8sacWGR8tkK4m9kjo5r"
[[test.validator.clone]]
address = "metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s" # implicitly also clones PwDiXFxQsGra4sFFTT8r1QWRMd4vfumiWC1jfWNfdYT

test.validator.account

Use this to upload an account from a .json file.

Example:

[[test.validator.account]]
address = "Ev8WSPQsGb4wfjybqff5eZNcS3n6HaMsBkMk9suAiuM"
filename = "some_account.json"


[[test.validator.account]]
address = "Ev8WSPQsGb4wfjybqff5eZNcS3n6HaMsBkMk9suAiuM"
filename = "some_other_account.json"
