I'll dig out the link later and post it here, but I am no longer offering Testnet loans via LN or on-chain transactions. I intend to donate some testnet bitcoin to Moccacino who is facilitating short term on-chain testnet loans (link to follow).
Should you wish to engage me to test the LN with testnet coins, I will do so on the stipulation you send to me and then I return to you (without collateral by me).
Mainnet LN loans are also down to
BTC 0.00001
and
BTC 0.0000101
repayment if more than 24 hours lent.
