Bourse.Currency (bourse v0.7.0)

Unified currency data.

Describes a currency or token supported by an exchange, including deposit/withdraw capabilities and network information.

Fields

id - Exchange-specific currency ID
code - Unified currency code (e.g., "BTC")
name - Full currency name
numeric_id - Numeric ID (some exchanges)
precision - Decimal precision
type - "crypto" or "fiat"
active - Whether the currency (or a network under networks) is considered usable. When derived from per-chain deposit/withdraw flags, the rollup is an authored per-venue decision (active_requires_both on the currency field map): true requires both directions, false accepts either. First-class venues must declare the flag; there is no silent default for them (task 482). Some venues (e.g. Binance coin-level) set currency active from a non-chain field such as trading — see that venue's carve register.
deposit - Whether deposits are enabled
withdraw - Whether withdrawals are enabled
fee - Default withdrawal fee
fees - Per-network withdrawal-fee map (%{} when none)
limits - Amount/withdraw/deposit min/max limits
networks - Network-specific deposit/withdraw info
info - Raw exchange response

The key set is the shared 14-key currency shape the static-response fixtures assert against; margin is deliberately absent, being a non-canonical extra only a few venues emit.
