description

Carbon decoder reference for Circle CCTP v2 Message Transmitter on Solana — program `CCTPV2Sm4AdWt5296sk4P66VBZ7bEhcARwFaaS9YPbeC`, crate `carbon-circle-message-transmitter-v2-decoder` (15 instructions, 3 account types, 11 CPI events). Use when decoding, indexing, or analyzing this program with Carbon: looking up instruction args/discriminators/accounts, account struct fields, or CPI event schemas. Run the bundled `scripts/carbon.py` to extract details from the local cargo cache.

Pulling full details

The plugin's scripts/carbon.py extracts struct fields, discriminators, and account variants directly from the decoder crate in your cargo registry cache.

# locate the script (it lives next to this plugin)
CARBON=$(find ~ -path '*/carbon-solana/scripts/carbon.py' -print -quit)

# list everything available for this protocol
python3 "$CARBON" list circle-message-transmitter-v2

# instruction details (args, discriminator, account variants)
python3 "$CARBON" ix circle-message-transmitter-v2 <InstructionName>

# account struct fields (and size constant)
python3 "$CARBON" account circle-message-transmitter-v2 <AccountName>

# CPI event fields + discriminator
python3 "$CARBON" event circle-message-transmitter-v2 <EventName>

# shared type fields
python3 "$CARBON" type circle-message-transmitter-v2 <TypeName>

# print the resolved cargo-cache path
python3 "$CARBON" path circle-message-transmitter-v2

Requires ast-grep and the crate to be present in ~/.cargo/registry/src/ (any cargo project that depends on carbon-circle-message-transmitter-v2-decoder will populate it after a cargo build or cargo fetch). If neither is available, run cargo install ast-grep and pull a project that uses Carbon.
