The following is reprinted here exactly as published in the Agora Marketplace Info/Help section.
Becoming a Vendor
To grant a Vendor account we require you to deposit 1.5 BTC which can be used up in case any disputes need to be resolved and you and the buyer cannot come to an understanding.
The deposit amount can be returned if you wish to seize your activities on Agora as a Vendor, and in case it has not been used up in any disputes.
To do this simply add the funds to your account using the Wallet page. When you have the needed amount on your balance, use the designated button on the Wallet page to receive Vendor status.
There are some ways to receive Vendor status without adding the deposit amount:
If you had a Black Market Reloaded (BMR) v1 or v2 account with feedback and can prove it with PGP, follow this guide: lacbzxobeprssrfx.onion/index.php/topic,74.0.html
If you had a Silk Road (original SR1) account and can prove it with PGP, follow this guide: lacbzxobeprssrfx.onion/index.php/topic,179.0.html
Additionally, if you verify yourself as described here as having accounts on those previous markets, a special badge will be displayed on your vendor page with statistics from those markets to help you reuse the users’ trust you have built up on those markets.
If you have outstanding history on other markets not mentioned here it’s sometimes possible to get a Vendor account without the deposit, but requires careful manual checking and can take long time.
