custom program error: 0x1
What it means
A transfer or account creation needs more lamports than the source account holds.
What to do
Fund the source account or lower the amount. Remember rent for any account being created.
Have the transaction that failed with this?
Paste its signature. TxWhy shows the exact instruction and inner call that raised the error, and rebuilds the transaction when the cause is one it can fix (compute limit, expired blockhash, priority fee, stale swap quote).
Code 1 means something else in other programs
Custom codes are private to each program. Check which program actually raised it: it is the innermost failed call, not necessarily the program you called.
