Problem
Solana swap visualizers (jupiter_swap, dflow_aggregator, …) resolve token symbols/decimals from a hard-coded 3-token table (get_token_info in chain_parsers/visualsign-solana/src/utils/mod.rs). There is no way for a wallet to supply token metadata, so most amounts render as raw base units or truncated mints. Ethereum already has the pattern we want to mirror.
Today
SolanaMetadata (proto/parser/parser.proto) carries only IDLs (idl, idl_mappings) — no token metadata.VisualizerContext (chain_parsers/visualsign-solana/src/core/) exposes only an IdlRegistry.- Ethereum:
EthereumMetadata.assets: map<symbol, TokenMetadata> → ContractRegistry::load_chain_metadata → format_token_amount (chain_parsers/visualsign-ethereum/src/{token_metadata.rs,registry.rs}), layered via LayeredRegistry (visualsign/src/registry.rs).
Proposal
- Add
assets: map<string, TokenMetadata> to SolanaMetadata in proto/parser/parser.proto (+ make generated).
- Extract it in
SolanaVisualSignConverter (core/visualsign.rs) and carry a token registry on VisualizerContext, layered over the static table via LayeredRegistry.
- Replace static
get_token_info lookups with a registry lookup so swap presets render symbol/decimals via create_amount_field.
Notes
- DFlow additionally needs ALT-resolved mints before its swap economics (
quoted_out_amount) can benefit — the output mint lives in an ALT-loaded account. The seam is documented in dflow_aggregator::push_swap_economics.
