# Systematic GOA withdraw ladder on bank.hacktivism.ch
|
||||
#
|
||||
# Per landing / intro docs:
|
||||
# 1) GET /intro/auto-account.json → personal goa-account-* (+ first pool URI)
|
||||
# 2) Shared pool withdrawals (explorer) with server auto-confirm
|
||||
# 3) wallet-cli: ToS + accept-uri + run-until-done each rung
|
||||
# 4) amounts from atomic-GOA up until bank/wallet fails
|
||||
#
|
||||
# Prefer the monitoring phase (random increasing ranges + timings + report):
|
||||
# ../taler-monitoring/taler-monitoring.sh ladder
|
||||
# LADDER_MAX_RUNGS=10 ../taler-monitoring/check_goa_ladder.sh
|
||||
#
|
||||
# Usage (standalone, fixed ladder):
|
||||
# ./goa-withdraw-ladder.sh
|
||||
# MAX_RUNGS=12 ./goa-withdraw-ladder.sh
|
||||
# AMOUNTS='GOA:0.000001 GOA:0.01 GOA:1 GOA:10 GOA:100' ./goa-withdraw-ladder.sh
|
||||
#
|
||||
# Env:
|
||||
# BANK default https://bank.hacktivism.ch
|

# EXCHANGE default https://exchange.hacktivism.ch/

|
