Estimate fees for BSV transactions based on size and fee rates.
# Estimate by size
bun run skills/estimate-transaction-fee/scripts/estimate.ts --size 226
# Estimate from raw tx hex
bun run skills/estimate-transaction-fee/scripts/estimate.ts --tx <hex>
# Estimate by inputs/outputs
bun run skills/estimate-transaction-fee/scripts/estimate.ts --inputs 2 --outputs 3
# Custom fee rate
bun run skills/estimate-transaction-fee/scripts/estimate.ts --size 226 --rate 2
# JSON output
bun run skills/estimate-transaction-fee/scripts/estimate.ts --size 226 --json
# Show help

P2PKH transaction size formula:
Example: 1 input + 2 outputs = 10 + 148 + 68 = 226 bytes
Default output:
Fee Estimation
==============
Size: 226 bytes
Rate: 1 sat/byte
Fee: 226 satoshis (0.00000226 BSV)
With --inputs/--outputs (shows breakdown):
Fee Estimation
==============
Size: 226 bytes
Rate: 1 sat/byte
Fee: 226 satoshis (0.00000226 BSV)
Breakdown:
- Inputs (1): ~148 bytes
- Outputs (2): ~68 bytes
- Overhead: ~10 bytes
JSON output (--json):
{
"size": 226,
"rate": 1,
"fee": 226,
"feeBsv": 0.00000226
}
