Si le statut de la transaction apparait en success ca veut dire que la méthode appelée a bien pu être traitée.
En regardant le contrat à cette adresse je trouve les fonctions suivantes sur ton token :
function transfer(address _to, uint256 _value) returns (bool success) {}
et
function transferFrom(address _from, address _to, uint256 _value) returns (bool success) {}
Tes fonctions sont tout simplement vides. C'est à dire que quand on les appelle, elle ne font....rien. D'ou le fait qu'il n'y ait pas de tokens qui bougent.
Il faut remplir tes fonctions avec les instruction de traitement afin de bouger les tokens d'une variable de mapping à une autre :
function transfer(address _to, uint256 _value) public returns (bool) {
if (balances[msg.sender] >= _value) {
balances[msg.sender] -= _value;
balances[_to] += _value;
Transfer(msg.sender, _to, _value);
return true;
}
return false;
}
et
function transferFrom(address _from, address _to, uint256 _value) public returns (bool) {
if (balances[_from] >= _value && allowed[_from][msg.sender] >= _value) {
balances[_from] -= _value;
allowed[_from][msg.sender] -= _value;
balances[_to] += _value;
Transfer(_from, _to, _value);
return true;
}
return false;
}

j'ai copié/collé ce contrat depuis le token ERC20 de wetrust ( très beau projet au passage avec des devs solides, j'ai eu la joie de me voir fournir un peu d'aide et d'apprentissage de la part de shine2lay
).
Tu feras attention, au survol du code j'ai constaté que d'autres fonctions de ton contrat avaient l'air vide.
Avant d'aller plus loin , je te conseille vraiment de passer par un outil de test type remix IDE :
https://remix.ethereum.org/Ca te permettra de tester le déploiement de tes tokens, les fonctions, etc. sur du réseau simulé, sur les testsnets. Ca t'évitera de te ruiner pour déployer des contrats sur un main net sans être certain que ceux-ci soient carrés.
Je t'ai mis les deux contrats également dans des gists sur github :
https://gist.github.com/anonymous/6e552ade5cb6e6377dd66d570649882fTu as juste à ouvrir RemixIDE, reconstruire les fichiers et go !
EDIT :
J'INSISTE ! quitte à passer pour un gros relou, mais arrête de tenter de déployer tes contrats sur le mainnet pour le moment, ca te coûte une foutue fortune pour pas grand chose. Utilise Remix IDE, creuse un peu le fonctionnement de tout le bousin, lis sur les différents outils que je t'ai linké, apprends à déployer sur ganache-cli/testrpc, puis à déployer & tester sur un testnet . Une fois que tu auras fait cela et que tu seras certain que tes contrats ne sont pas buggués et qu'ils sont construits correctement alors ET SEULEMENT ALORS tu pourras déployer sur le main net.
Sans ça, tu te ruines pour rien.
No offense hein, après tout ç'est pas mon argent qui part pour rien, mais ca m'embête un peu de te voir claquer de l'argent pour rien.
