In `@crates/minibf/src/mapping.rs`:
- Around line 1034-1039: The conversion of the donation field fails because
.as_ref() yields &Coin and u64::from isn't implemented for &Coin; update the
treasury_donation construction (involving tx.as_conway().and_then(|x|
x.transaction_body.donation.as_ref()).map(...).unwrap_or_default().to_string())
to convert the referenced Coin into a u64/string by mapping the reference to an
owned or directly into a string (e.g., use .map(|c| c.to_string()) or .map(|c|
(*c).into().to_string()) or .map(|c| c.into()) on the owned value) so that the
donation is properly converted without relying on From<&Coin>—adjust the map
closure in the treasury_donation expression accordingly.
In `@crates/minibf/src/routes/accounts.rs`:
- Around line 326-328: Replace the silent casts for tx_slot, block_time, and
block_height with checked conversions (use i32::try_from or .try_into()) on the
values returned by block.slot(), chain.slot_time(block.slot()), and
block.number(); handle and propagate the conversion error the same way the
codebase does elsewhere (return an Err with context) so overflow doesn’t
silently wrap. Apply the same change to the other occurrence of these fields
around the block at the second location (the lines referenced 372-374).

The u64::from conversion after .as_ref() will fail to compile because From<&Coin> is not implemented for u64.
After .as_ref(), the donation field is a reference (&Coin), but u64::from only accepts owned Coin values. The working pattern in crates/cardano/src/pallas_extras.rs uses .map(|x| x.into()) on owned values. The proposed fix correctly converts the referenced donation directly to a string.
🐛 Proposed fix
let treasury_donation = tx
.as_conway()
.and_then(|x| x.transaction_body.donation.as_ref())
- .map(u64::from)
- .unwrap_or_default()
- .to_string();
+ .map(|donation| donation.to_string())
+ .unwrap_or_else(|| "0".to_string());📝 Committable suggestion

# Let's verify the practical risk: Cardano mainnet, current era
# Byron era ended ~2020, Shelley era started. Let's see what values are realistic
# A conservative estimate: mainnet launched in 2017, slots are ~1 second
# Current date is April 2026, so roughly 9 years * 365 days * 86400 seconds ~ 280 million slots
# This fits in i32 (max 2^31-1 ~ 2.1 billion), but converting is still unsafe practice

Use checked conversions for the new block metadata fields to prevent silent overflow.
block.slot(), chain.slot_time(...), and block.number() return u64 values; casting to i32 silently wraps on overflow. While Cardano's current state won't overflow for years, implement defensive conversion with error handling to match the pattern already used elsewhere in the codebase.

In `@crates/minibf/src/routes/accounts.rs` around lines 326 - 328, Replace the
silent casts for tx_slot, block_time, and block_height with checked conversions
(use i32::try_from or .try_into()) on the values returned by block.slot(),
chain.slot_time(block.slot()), and block.number(); handle and propagate the
conversion error the same way the codebase does elsewhere (return an Err with
context) so overflow doesn’t silently wrap. Apply the same change to the other
occurrence of these fields around the block at the second location (the lines
referenced 372-374).
